Customer Identity / CIAM # Customer Identity / CIAM Sign-up, login, and identity for end users and customers. 18 vendors · Last updated 3 weeks ago Quick answer ## What is Customer Identity / CIAM? Short answer CIAM platforms handle high-volume consumer or B2B login, registration, social sign-in, progressive profiling, and consent management. Best for Product, growth, and engineering teams building customer-facing apps or B2B SaaS platforms. When to choose Evaluate developer experience, B2B vs B2C fit, scale, social and enterprise SSO, fraud signals, and cost at your expected MAUs. When not to choose Skip Customer Identity / CIAM tooling if a broader IAM platform already covers your needs and you don't have category-specific requirements.
